CES Nvidia has rolled out the GeForce GTX 285 and 295, the two top-end GPUs it was expected to announce this week.

Nvidia's GeForce GTX 285: world's fastest one-GPU board?

The 285 is a single-GPU product that Nvidia claimed was 30 per cent faster than rival one-chip graphics cards. Boards based on the 295 design contain two GPUs. Both types of board are two-slot cards.

The 285 contains 240 unified shader processors, with the core as a whole running at 648MHz. Its 1GB of GDDR 3 is clocked at an effective 1242MHz. By comparison, Nvidia's existing GeForce 280, launched last summer, runs at 602MHz and 1107MHz, respectively.

GTX 295: ready for Quad SLI

Each core on the 295 board runs at 576MHz. The memory's clocked at 999MHz.

It's available from usual-suspect graphics card suppliers now. The GeForce GTX 285 will go on sale next week, on 15 January. ®
